Synchronization and Data Refresh Strategies

Combine synchronization and data refresh techniques and strategies to successfully meet the business needs of the mobile application while effectively utilizing resources.

• Design and planning – carefully consider:
  • Limiting data in the mobile business object (MBO) to what is required to meet business needs.
  • The size and scope of the mobile application.
• Timing – coordinating device application synchronization with data refresh to achieve optimum results.
• Methods – use a combination of methods to control how much data in the Unwired Server cache is updated when EIS data changes. It is relatively simple to design your system to invalidate MBO data in the CDB and refresh it from the EIS whenever EIS data changes, but this can be inefficient.

• Synchronization Scenarios and Strategies
  Mobile application development and administration settings allow you to decide when and how to synchronize and refresh data.
• Bulk Loading Cache Strategy
  Bulk loads transfer large quantities of data into the consolidated database (CDB), which acts as the Unwired Server cache. Because of the demands this places on resources, special consideration needs to be given when using this strategy.
• On-Demand Loading Synchronization Strategy
  On-demand loads transfer a specific subset of data when the exact data required cannot be predetermined at design time, especially when space and performance demands imposed by bulk loading is an issue in the production environment
• The Impact of Synchronization and Data Refresh
  When designing and developing your mobile application solutions, consider the impact of varying synchronization and data refresh methods.
